The Midcontinent Rift: Earth's Failed Split

TLDR1.1 billion years ago, the Midcontinent Rift attempted to split North America in half, resulting in the formation of a huge scar called the Midcontinent Rift. This rift was caused by passive rifting and the presence of a mantle plume. The rift eventually stopped due to the separation of the continents and the relief of stress on the continent. The Midcontinent Rift is now the deepest known rift on Earth that didn't form an ocean.
